This study introduces a novel ceramic-composite resin specifically developed for stereolithography (SLA) 3D printing, aimed at enhancing dental restorations. The integration of advanced digital technologies in dentistry has shifted traditional methods towards more precise and efficient techniques such as computer-aided design/computer-aided manufacturing (CAD/CAM). However, these processes typically involve material waste due to their subtractive nature. Additive manufacturing, or 3D printing, particularly SLA, which uses ultraviolet light to cure photosensitive resins, presents a viable alternative with the potential for creating detailed, custom restorations with minimal waste. Our research focuses on formulating and evaluating a ceramic-composite resin that combines the benefits of light-cured materials with the mechanical robustness required for dental applications. We conducted comprehensive tests to assess the printability, mechanical properties and wear resistance of the developed material. The ceramic-composite resin demonstrated a tensile strength of approximately 73 MPa, significantly higher than the 42 MPa observed for traditional photopolymer resins. Additionally, the ceramic-composite resin showed ability to resist incidental friction and wear. This research could significantly impact the dental prosthetics field by providing a method for producing high-performance, patient-specific restorations efficiently and cost-effectively.

Šiame tyrime pristatoma nauja keraminė kompozitinė derva, specialiai sukurta stereolitografijos (SLA) 3D spausdinimui, kuria siekiama patobulinti dantų restauravimą. Pažangių skaitmeninių technologijų integravimas odontologijoje pakeitė tradicinius metodus, pereinant prie tikslesnių ir efektyvesnių metodų, pavyzdžiui, kompiuterizuoto projektavimo ir kompiuterizuotos gamybos (CAD/CAM). Tačiau šie procesai dėl savo veikimo pobūdžio medžiagas yra linkę švaistyti. Pridėtinė gamyba, arba 3D spausdinimas, ypač SLA, yra perspektyvi alternatyva, galinti kurti tikslias, individualias ir lengvai pritaikomas dantų koregavimo ir atkūrimo priemones. Šiame straipsnyje pagrindinis dėmesys skiriamas keramikos kompozito dervos, pasižyminčios mechaniniu tvirtumu, reikalingu dantims restauruoti, spausdinimo galimybių įvertinimui. Atlikti išsamūs mechaninių savybių ir atsparumo dilimui bandymai parodė kompozitinės dervos 73 MPa stiprumo ribą, kuri yra gerokai didesnė nei tradicinės fotopolimerinės dervos (42 MPa). Taip pat nustatyta, jog keraminė kompozitinė derva pasižymi atsparumu atsitiktinei trinčiai ir dilimui. Šis tyrimas turi praktinės reikšmės dantų protezų gamybai, nes suteikia galimybę efektyviai ir pigiai gaminti aukštos kokybės, pacientui pritaikytus dantims restauruoti skirtus gaminius.
